AC VOLTAGE MEASUREMENT (contact or non-contact techniques)
Set the selector switch to measurement range V~.
Insert the black test lead into the 'COM' socket and the red test lead into the right-
hand socket. Using the test probes, touch the test points of the test object.
The multimeter automatically searches for the most suitable measurement range.
Read measurement value on the display.
The display blinks and an acoustic signal is emitted when, with the M-button held
pressed down, the top edge of the multimeter is held up to a live conductor (100 –
400 V AC). The instrument functions in the same manner during a single-pole
phase test using the red test lead.
DC CURRENT MEASUREMENT:
Set the selector switch to measurement range A≅.
Use the 'M' button to set the device to DC.
Insert the black test lead into the 'COM' socket and the red test lead into the right-
hand socket (up to max. 200 mA).
You must use the '4 A' socket when measuring currents above 200 mA.
Using the test probes, touch the test points of the test object.
The multimeter automatically searches for the most suitable measurement range.
Read measurement value on the display.
AC CURRENT MEASUREMENT:
Set the selector switch to measurement range A≅.
Use the 'M' button to set the device to AC≅.
Insert the black test lead into the 'COM' socket and the red test lead into the right-
hand socket (up to max. 200 mA).
You must use the '4A' socket when measuring currents above 200 mA.
Using the test probes, touch the test points of the test object.
The multimeter automatically searches for the most suitable measurement range.
Read measurement value on the display.
RESISTANCE MEASUREMENT:
Set the selector switch to measurement range 'Ω'.
Insert the black test lead into the 'COM' socket and the red test lead into the
'INPUT' socket.
Using the test probes, touch the test points of the test object. The multimeter
automatically searches for the most suitable measurement range.
Read measurement value on the display.
